4 Claims.

provide an accurate non-slipping joint at any bent edge of any box-like structure such as a pasteboard box which is to be used as a sub-' stitute for the well known type of wooden cigar box which is substantially rigid and in which the short sides or ends stick'up above the long sides or front and back and the cover is hinged at the back so that when the box is closed it rests between the ends, the cover usually being fastened at the front by means of a tack.

Objections to other boxes for cigars made of pasteboard are that the edges slip and the fastening strips break. This box is easily puttogether by well known machines and when finished is not only rigid, but as the adjoining edges both vertical and horizontal are preferably provided with rectangular scores, channels, grooves or recesses, the sides .and bottom are held firmly in place.

Preferably I then use one or more holding strips on some of the edges and one or more sheet members, or one or more sheet members alone'without the strips, glued or stuck to the outside of the box members whereby the box is kept firmly together with adjoining sides and edges always kept at ninety degrees with each other.

By extending a sheet member around and sticking it to the outside vertical edges and also to the bottom edges, the adjoining wall edges and bottom edges are firmly kept and held at right angles to each other.

In the drawing, Fig. 1 is an elevation of a wall member such as I prefer to use.

Fig. 2 is an enlarged plan view showing in detail the preferred type of scores and the preferred type of pasteboard wall member before bending.

Fig. 3 is a horizontal section-of Fig. 2 after bending.

Fig. 4 is a vertical section somewhat enlarged showing part of the wall member, part of the bottom member and part of the holding sheet member.

Fig. 5 is a perspective view of a box of my preferred construction bottom side up with parts broken away to show the construction.

Fig. 6 is a vertical sectional detail showing a modification of the recess arrangement between the bottom edge of a wall member and a bottom member.

Fig, 'l is another vertical sectional view showing still another modification of the relation between the recess or recesses and the bottom edge of the wall member and the bottom member.

Fig. 8 is a perspective of a complete and finished box of my preferred construction.

Fig. 9 is a horizontal section showing another 5 method of uniting the edges of the wall member.

Fig. 10 is a plan view showing another method of uniting the vertical edges of the wall member.

In the drawing, A represents what I will call a wall member or bendable box blank which may 10 embody all or part of the faces of a complete box made from a sheet of substantially rigid cardboard or pasteboard preferably of about the thickness of a wall of a. cigar box. This wall member A is cut from the sheet by any suitable mechal5 nism and as shown in Fig. 1 is so cut that it is divided into four sections 1, 2, 3 and 4 by vertical scores indicated by T T and T The sections 1 and 3am higher than the sec-' tions 2 and 4 and the ends of the wall'member 20 A which arealso the ends of the sections l and 4 are mortised as shown at 8 and 9 in such a waythat when brought together to form the walls or sides of the box, these vertical ends 8 and 9 interlock and by friction tend to hold the four sections of wall member A in position in the shape of a rectangle. I

The scores T T and 'I are on the inside and there is also an angular recess S which is preferably continuous along the inside bottom of 30 member A to receive a bottom memberB of substantially rigid cardboard which .fits into said recess or recesses and thus holds the whole box in rectangular position.

The member A is folded and the ends 8 and 9 interlocked as describedafter which the bottom member B'is slipped into the recess S and while being held in position, a holding sheet member C is bent around and stuck to substantially all of the outside of the four walls L2, 3 and 4 and part way around the bottom edges onto the outside of bottom member B to which it is stuck.

This holding sheet member firmly holds the whole box together. Such a sheet member C, however, as shown in Fig. 4, may. be entirely omitted, or it maybe replaced by a gummed strip of paper or cloth over the open joints or by glue between the contacting parts or even by nails such as 83, as shown in Fig. 9, or by any other suitable means for holding such contacting parts together.

My preferred form of scores include a deep channel such as Y and a contiguous shallo channel X as shown in Fig. 2.

These channels are cut by suitable knives and gouges and have clean out straight sides and ed es.

l teferring to Fig. 2, 40 is the inside edge of the shallow channel, 4| the adjoining side, 42 the outside edge, 43 the outer side, 44 one edge which adjoins the deep channel Y, 45 the shallow side of deep channel Y, 46 and 48 the outside edges and 41 the outer side of deep channel Y, 49 the long side and 50 the inside edge of channel Y.

When folded, the inner face 5| of wall A abuts on inside edge 40 and side 4| of shallow channel X whilethe inside edge 50 of deep channel Y engages the outside edge 42 of shallow channel X and the edge 48 preferably engages the edge 44, the bend coming substantially at the edge 46. By using a score with channels of two depths the part between the outer side .41 of the deepchannel and the outside face of wall A can be made very thin because when the inside edge 50 en'- gages the outside edge 42, particularly if the distance from 48 to 50 is the same as from 42 to 44,

the parts are locked firmly in place and no slipping is possible. This permits the web between 46 and 48 to be thin and it neednot beas strong as if there were a side strain or slipping strain of a sheet which can be printed or lithogrjaphed and will give a good finish to the'inside while the outside layer such as 52 should be of jute r craft stock which can be readily bent to form a cleanout edge such asat 53.

The interior 54 of wall member A can be of any cheap stock to give body to the walls. Preferably the sides of the vertical scores should be parallel and the bottom or bottoms parallel with the irmer face such as 5| of the'wall mem-.

ber and should makearight angle-with the sides.

Instead of the angular recess S in awall mmber A, as shown in Figs. 1, 4 and 5,43. wall member K with no recess at the bottom can be used,

the lower edgefn fitting into. an angular recess 9| which extends around the inner edge of a bottom memberL. I j 7 1 f Asanother alternative-a wall member92 can have an angular recess 93 similar 'to S-and' the corresponding bottom member 94 can have an angular recess 95 corresponding with 9|.

While the mortised construction at 8 and 9 is 5 preferable, as shown in Fig. 9, I may join the free vertical edges such as 8|! and 8 of my wall member by fitting the end of 80 into the rectangular channel 82 inthe other end 8| and holding the I parts together by one or more tacks 83 over which preferably would be stuck a holding strip 84. As shown in Fig. 10, the tacks could be omitted holding sheet while P is a cover also madeof pasteboard fastened to .the box proper along the edge 99 by any well known device such as a strip of cloth such as used in wooden cigar boxes.

A single holding sheet member such as C or two holding sheets such as C and O can be used.

Some part of the bottom member such as B, L or 94 should fit inside the wall member to hold the box firmly in shape.

While I have shown and described my preferred construction of a box forming substantially a rectangular parallelepiped, it is obvious that the angles of the sides of the scores in the wall member could be varied to correspond with the angles made by the adjoining edges of a bottom member if these edges made acute and obtuse angles with each other.

.It is obvious that where the terms bottom, top and sides are used in this description, these terms may be interchangeable and that a side may become an end, a top or a bottom according to the position in which the box is placed. Moreover where the term inside is used, it means the inside of a boxfor boxlike structure or more specifically it means that side or face of the material from which-any particular score is cut and towards which-the two sections-which adjoin that r --score are bent. By outside is meant what is. ultimately the outside of the box or boxlike structure, or more particularly the other side or other face of thematerial not the inside, or theside from which the score is not out. 'By top edge with reference to a score or channel is meant anedge at theinside face of the material and by bottom edgeor side is meant an edge or side of a score or channel which is' nearest the outside face of the'material. i

. The faces of the channels which are substantially at. ri'ght angles to the faces of the material may be called the walls while the faces which are parallel with the faces of the material may be called the bottoms of the respective channels'.-y.,. I 4

One of the most'common uses of this invention is a part of a pasteboard box and may be called abendable box blank but it can also be used in connection with what is known as beaver board or wall boardfor the vertical joint at a corner of aroom. Such a room, I' call a boxlike structure and, ofcourse, a two step joint such as I claim herein can befused, as indicated in the suchas |,I2, 3 and .4, but it might have any less or greater number of sections provided there are twoor more.- In other words, I,claim to be the first to provide a bendable or angularly bent blank ofsubstantially rigid cardboard having one or more scores each score having a deep cut channel and a contiguous shallow .cut channel sections.

It is also obvious that all of the sections, whether two or more, may or may not be of the same height or size and it is also obvious that a box such as shown-inFig. 5 maybe rested on the small end which then becomes the bottom whereby B would be the front or back and sec- 1 tion, glue or in any other manner such, for instance, asby nails like 83 shown in Fig. 9.

Obviously such a section I might be omitted whereupon such a box would have an open top.

60- whereby such blank is divided into a plurality of The principal feature of the invention is such a bendable or bent blank of sheet material having in one face a straight score which includes a shallow channel and a contiguous deep channel, both out instead of bent from the material, whereby the blank can be bent along the web of material at the bottom of the deep score and when so bent will have a multiple depth interbraced angular joint between any two adjacent sections.

I claim:

l. A bendable box blank for a rigid pasteboard box made of substantially rigid cardboard having an outside layer of tough bendable material and being divided into sections by a score cut from the inside which comprises a deep channel and a contiguous shallow channel, the sides of said channels being parallel with or at right-angles to the face of the cardboard so that when the adjacent sections are bent at right-angles to each other the inside edge of the deep channel rests in the angle along the outside edge of the shallow channel to form a multiple depth interbraced angular joint between said sections.

2. A blank for a boxlike structure, which blank is made of substantially rigid cardboard or other similar material and is divided into sections by a score cut from the inside of the material, which score comprises a deep-cut channel and a. contiguous shallow-cut channel, the adjacent sections being bent at the web at the bottom of the deep-cut channel sothat the top edge of the deep channel rests in the angle along the bottom edgevof the shallow channel whereby a multiple depth interbraced angular joint is formed between said sections.

3. A blank for a boxlike structure which blank is made of substantially rigid cardboard or other similar material which can be bent when scored and which is divided into sections by a score cut from one side of the material, which score comprises a deep-cut channel and a contiguous shallow-cut channel, the channels being so cut and of such size that the adjacent sections can be bent at the web at the bottom of the deepcut channel and when so bent that the top edge of the deep channel will rest in the angle along the bottom edge of the shallow channel whereby a multiple depth interbraced angular joint can be formed between said sections.

4. In a box, the combination of a bendable box blank made of substantially rigid cardboard or other similar material which is divided into sections by a score cut from the inside of the material, which score comprises a deep-cut channel and a contiguous shallow-cut channel, the adjacent sections being bent at the web at the bottom of the deep-cut channel so that the top edge of the deep channel rests in the angle along the bottom. edge of the shallow channel whereby a multiple depth interbraced angular joint is formed between said sections; with another sec- Y tion rigidly fastened to the bent blank to strengthen and hold the parts in place.
